I noticed that my 6 year old gas water heater (50 gallon) is making a constant noise similiar to a loud wind up clock but otherwise it is working fine. I drained the tank and I still notice the sound but it is not quite as loud as before. When I drained the tank the water ran clear without any sediment. When I hold my ear up to the water heater the sound is definitely coming from inside the tank. Does anyone have any idea what the noise is?
Thanks,
Stan

electric or gas water heater????

WOW!!! What a Ride!

Well, you probably didn't get the sediment out of the heater, though doing so would not necessarily eliminate the noise. To reasonably flush the heater you generally need to partly drain it (be sure to cut power/gas) and then repeatedly turn on and off the inlet valve, to stir up the layers of muck on the bottom of the unit.
Please describe the process. Let's say I have a gas heater. So. I drain the tank first? Then leave the drain open and repeatedly open and close the cold water inlet? What's the timing on the open/shut cycle?Thanks,

You turn it on full-bore for 15-30 seconds, then let it drain, then turn it on again. You don't need to have the tank fully drained but it should be at least half empty.

Tanks, for whatever reason sometimes make noise just like a ticking clock and it has to do with expansion and contraction. Heating and cooling. I have heard it many times.
I'm thinking that when you drained it and still heard the noise but slightly less is maybe that it was now cooling (contracting) and there wasn't any water in it to amplify the sound.
A few months ago I was working on some equipment and I kept hearing a loud ticking noise close by but with being busy and the general noise of the place I didn't investigate it.
A couple of days later one of the workers came over to have a chat and I mentioned the ticking. He pointed to this huge high pressure air tank about 5 feet in diameter and about 12 feet high. He said it always did it.
I wasn't impressed but always tried to keep the machine I was working on between me and the tank. Fat lot of good that would do if it blew but I felt I had to at least do something:)

Thanks Roger & Others:
The water heater has stopped making noises but when I was checking the unit out initially, I operated the pressure relief valve and now it leaks about a cup full of water per day.

You have just discovered the reason why we service people NEVER touched the T/P valve unless we had another in our van:)

Operate the valve several more times to see if you can dislodge any crud in there and reseat it. If that doesn't work it's replacement time.
If your view never changes you're following the wrong leader
